Abstract
A frame constitutes the main part of a gradually released tension machine, which is a kind of tool for tensioning and releasing cargo binding strips by hand, and which also comprises a ratchet and an operating handle. On the edge of the frame is a locking slot and a loosening slot, and a releasing slot near the loosening slot. The frame also has a slow-release device comprising the releasing slot and a sliding gear which is used in combination with the ratchet of the tension machine and is rotatably fixed in proximity to the releasing slot, such that the tip of the sliding gear overlaps the releasing slot and is substantially even with the teeth of the ratchet. The frame is simple and can be easily manufactured. Utilizing this kind of frame, the releasing effect is much better, and the tension machine has greatly improved reliability and safety.
